Specification of Ietters Patent. Application filed J'uly 1i, 191a.swarm. 778,482.

Patented Sept. 1, 1914.

To all whom it may, concern:

Be it known that we, LUES Rnrrnu and,

HARRY FULFORD, citizens of the United States, and residents of the cityof Providence, in the county of Providence and State of Rhode Island,have .invented certain new and useful Improvements in SeparableFastoners, of which the following is a specifica-' folded outward neartheir middle portion and the periphery of said plates being rolled overthe free ends of said fingers so as to yieldably retain them inposition, whereby the head of a complemental stud may be readily passedinto said socket and removably but firmly secured thereto.

The invention further consists in providing the outer, plate with acentral opening and rolling the stock around said opening inward toprovide a bead over which the outer member is rolled for permanentlysecuring. the whole in position on the goods.

A further object of the invention is to' swage the stock of the fingersslightly inward at a point between the base and the bend therebystiffening the stock of the fingers and providing a contracted neckportion through which the head of the stud must, pass to enter theenlarged portion within adapted to receive it.

With these and other objects in view, the

inventionconsists of certain novel features of construction, as will bemore fully described and particularly pointed out in the appendedclaims.

Of the accompanying drawings: Figure 1 is an enlarged sectionalelevation showing the socket member ermanently secured by means of thecap to t e material or goods and the stud in position to enter thesocket. Fig. 2 is a plan view showing the shape of the-blank from whichthe socket member is formed. Fig. 3- is a sectional elevation showinganother step in the operation wherein the blank is bent to form an innerand outer plate and a plurality of fingers extending outwardly from saidinner plate. Fig. 4- is a sectional elevation showing the finishedsocket member with the ends of the fingers extending under the rolledover periphery of said plates and the edge of the stock around thecentral aperture in the outer plate being rolled inward to form "a bead.Fig. 5 1s a plan view of the socket member.

Our improved socket member is preferably formed froina single piece ofsheet metal, the same being provided with a plu-. ralitv of fingers 10,thenumber preferably employed being four. The outer ends of thesefingers are preferably formed with a V-shaped notch forming points 11--11 which are adapted to be more readily bent to passunder and beengagedby the rolled over .peripheral edge presently described. The bodyportion of this member is bent into the form illustrated in Fig. 3comprising an outer plate 12 preferably bent into a concavo-convex shapeand than doubled practically upon itself forming an inner plate13 havingits outer edge integral with that of the outer plate 12. The fingers 10are formed to extend outward from this inner plate and are bent neartheir middle portion, as at 14, said'bent over portion 15 extending on.an outward angle with its pointed ends resting on the inner plate andnear its periphery. That portion of the fingers between the bend and theinner plate isofiset inwardly as at 18 forming a contracted neck portionand a comparatively enlarged inner socket portion for receiving andretaining the head of. the stud 19, see

Fig. 1. In order to secure the ends of thesefingers in position theperipheral folded edge 16 of these plates 12' and 13 is rolled inwardforming an undercut or groove '17 intowhich these finger ends extend.The outwardly extendingportion 15 of the fingers serve to stiifen andsupport their gripping neck portion whereb said fingers Wlll retain thehead of the stud in its socket portion against considerable strain towithdraw it. I

It is found in practice that where fasteners of this character-areapplied to such small light articles as ladies gloves and the like, thatthey should release with a comparatively slight pull, but Wherefasteners of this character are applied to suspenders, automobile tops,clothing, and the like, where it is necessary to resist considerablestrain, it is found necessary to supportand stiffen the gripping fingersso that they will resist considerable strain and will not permit thehead to be too readily drawn from its socket, therefore to accomplishthis our present construction provides supports for said fingers set onan angle thereto to extend from the peripher of the plate to the outerorengaging en s of said fingers to support and materially stifii'enthe'same.

Another feature of this invention is that the outer plate 12 is providedwith a central -opening 20, the stock at the edge of which is. rolledinward as at 21, see Figs; 1 and 4, providing a head which serves adouble purpose, first, to stiffen the-stock at this point around-theopening, and second, toprovide a means for retaining the neck of thecap,presently described. This socket member is designed to be permanentlysecured to the article or goods a by means of a cap member 22, said capmember being provided with an enlarged finished head 23 and a neckportion '24 the end 'of the stock at the neck portion being adapted to.be passed through a hole in the goods and through the opening-20 in theouter plate 12 of the periphery of said base being folded upon the endsof said fingers to clamp them in position.

2. A socket member consisting of a single sheet ofmaterial bent uponitself to form a base comprising inner and outer plates, the

inner edge of said inner plate having a plu-- rality of integral springfingers bent downwardly with their ends resting upon the outer ed e ofsaid inner plate, saidtongues being 0 set between the bend therein andsaid inner plate to form an enlarged socket, and the periphery of saidbase being folded uponthe ends of said fingers to clamp them inposition.

3. In a separable fastener, a socket memberconsisting of a single sheetof material bent upon itself to form a base comprising inner and outerplates, said outer plate having a central opening, the inner edge ofsaid lnner plate having-a plurality of spring tongues bent downwardlyand outwardlyv with their ends resting upon the outer edge of said innerplate, the periphery of said base being bent upon the ends of saidfingers to clamp them in position, and means passing through the openingin said outer plate and engaging the periphery thereof for securing saidsocket upon a fabric.

In testimony whereof We affix our slgnatures in presence of twowitnesses.
